New crankshaft position sensor with new pcm

[02suburbanZ71]

Okay i got my blackbear tune a while ago and because of my issues they have my tune saved on a new pcm they have sent me and they told me my truck would not need a crank relearn with the pcm i received from them because it was a complete duplicate. But 2 days ago i had a new camshaft position sensor installed and i'm wondering if i'll get codes after swapping the other pcm in because the 2nd pcm did not receive a relearn for the new cam sensor. So basically i'm swapping my original tuned pcm with the new camshaft location with a new pcm with my tune but old cam sensor

You are probably best just to email Justin and ask him. Not sure why you put the stock pcm back in though before the sensor relearn. Dealer gave me no issue at all to do the crank relearn on mine with the modified pcm. The relearn does not alter the tune. Mind you I told the dealer the pcm was changed and modified to work with the 4.10 gears. They know not to flash it without asking first due to this.

I emailed him a couple days ago. I only have 1 pcm my original, but they sent me one so i could send them mine
